Add a redirect for mc admin config

[djwfyi]

Describe the bug When in the Console, go to Settings > Configuration. The link points to https://docs.min.io/minio/baremetal/reference/minio-cli/minio-mc-admin/mc-admin.config.html?ref=con#id4, which results in a 404.

We need to add a redirect to https://docs.min.io/minio/baremetal/reference/minio-mc-admin.html (not an exact fit, but in baremetal) or https://docs.min.io/docs/minio-admin-complete-guide.html#config (legacy doc)

To Reproduce Steps to reproduce the behavior:

1. Login to the Console at play.min.io
2. Click on 'Settings'
3. Click on Configuration
4. Scroll down to bottom the screen
5. Click on the Documentation link
6. See 404

Expected behavior A good link that informs the user about the functions available with mc admin config.

Additional context N/A
